More resources to VirtuaBox

[pawelfaron87@wp.pl]

Sorry in advance If this was disused before. I've tried to find something but I've found solution only for Ubuntu.
I'm using VirtualBox for most of the work - compilation, test running, simulation - and I wanted to give it as much resources as possible. I'm using Windows 7 64bit.
There is problem with setting priority which was disused on this forum (the Access Denied error). So do you know some way to give more resources to VM.
I'll thankful for any advice.
